Ah! Se eu soubesse isto antes!

A great Video on Silicone Molds.

Note the main Tip, is that you add more Corn Starch each time you mess with the "dough", so to speak. 

Saves a lot of stress...

Pocket Pi - a Raspberry Pi Computer for Under $150
TheInventionMaker

This is a affordable $100 raspberry pi computer. This computer is not the thinnest or prettiest thing on instrutables. This is for getting the job done. The shell is 3D printed. There is 1 charging port, for the motherboard. The keyboard has a wire designated for charging the keyboard and will not be noticeable on the outside. There are 3 USB 2.0 ports are for input. 1 will be used by your bluetooth + wireless USB stick. Luckily, I have included a USB holder that holds your USB's.

The screen is 4.3 inches and is not a touchscreen. You can easily make it touch screen compatible. The raspberry pi is a zero. This is because the Adafruit Kippah currently does not support the zero w. You will still need a wifi network! It runs NOOBS, but you can still download PC games on it. All you have to do is to search on google how to install PC games on NOOBS.

You can use this to check up on things, play games, and use applications that are normally on PCs. It can do a lot of things that phones can do, but the computer is significantly cheaper. The parts are spread across 3 different websites. If you do not have a 3D printer or a soldering iron, you will have to but different parts. This will be explained in the steps. It should take you around 1 hour to build, but with shipping times and how long your 3D printer takes to print the parts, it could be longer.

A Pocket $200 Night Scope, now, that sounds real Neat!

3D Printed Night Vision Scope

Happy_Mad_Scientist

Hey everybody!!! Hows it going?!?!?! Ok, so for a long time (~3 yrs.) I have been building these digital night vision cameras, and after over $1,000 and hundreds of hours in R'n'D later, I give you the "Eagle Scope 1.0" (named after the camera inside)!!!
It's a pocket-sized, 3d printable night vision monocular that you can build yourself for ~$200!!! Oh, and it is top of the line, sporting a near-eye display (that doesn't burn out your eyeball), a .00001 lux camera with an OSD, a rechargeable 3hr battery, and an (optional) external DVR for recording the footage!!! Best of all, it fits in your pocket!!! Over-enthusiastic!!!!!! But seriously, this thing kicks some major buttocks.

Um Motor feito com Ímanes Permanentes, que é um Anel, com a Hélice no meio!
Vejam o Vídeo, para perceberem as vantagens dum tal Sistema, que vale a pena...

Rolls-Royce | Permanent Magnet Technology

The AZ-PM thruster is the latest in a range of Rolls-Royce propulsion products using its permanent magnet technology. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. The rotor, fitted within a series of magnets, turns within an outer ring which form the stator. When current is supplied to the motor from the variable frequency power supply the electromagnets are excited in a particular sequence and the resulting magnetic fields interact with the field from the rotor magnets creating a torque that turns the rotor and its propeller blades.
